My Great Grandfather Benjamin Williams was in the Welsh Regiment (service number 16624) and also in the Machine Gun Corps (service number 25263).I have his medals as a starting point, but not a great deal more. Trying to find a Welshman called Williams - Tricky to say the least, especially without a date of birth. I would love to know which battalion he was in. Also, was the Machine Gun Corps attached to The Welsh Regiment or a seperate unit? Any thoughts on this would be appreciated. Thanks Sue.
